Nuclear Drain Equipment from Top Flight Tasking Ltd.

TFT products have ranged from simple devices to carry cameras and radiological probes down drains and bore holes, to complex manoeuvring tracked and wheeled vehicles (ROVs). The latter can carry a variety of operational equipment and are suitable for use in many hazardous situations including high radiation, toxic and explosive risk situations. All equipment is designed and produced to suit the customer’s particular requirements

Vehicles: For the larger drains (150 mm dia and above) wheeled vehicles have been produced, carrying cameras, lighting, one or two radiological probes and sampling equipment. The vehicles are wheeled and electrically powered through an umbilical up to 100 metres long. This also carries the video and radiological signals and the command signal.

In Drain Devices (IDDs): For drains smaller than 150mm dia, smaller devices have been produced and these are propelled with standard high quality locking drain rods. These IDDs are also equipped with a camera, lights and one or two probes and can produce the same information on the condition and contamination of the drain, as the larger vehicles.

Supporting Equipment: The umbilical from the drain device or vehicle is connected to a base station that provides power, and processes and records the data. The base stations are man portable and designed for rugged site work. They require only 110v input and enable the operator to control the vehicle and monitor the view from the front of the vehicle, on his CCTV screen. Superimposed on that screen are the counts from the radiological probes, the distance that the vehicle has travelled down the drain and any information that the operator wishes to add, using a standard IBM computer keyboard. All this is captured on a video recorder, together the audio produced by the probes and with any verbal information from the operator.
